System and method for measuring hydrogen content in a sample

摘要

A measuring method including the steps of providing a chamber, drawing a vacuum in the chamber, placing a sample into the chamber, heating the sample to desorb a target species from the sample, passing a carrier gas through the chamber, the carrier gas mixing with the desorbed target species to form a mixture, and analyzing the mixture.

1. A measuring method comprising the steps of:
drawing a vacuum in a chamber; placing a sample probe into said chamber, said sample probe defining an internal bore, wherein said internal bore is fluidly isolated from said chamber outside of said sample probe; heating said sample probe to desorb a target species from said sample probe; feeding a carrier gas into said chamber outside of said sample probe by way of a first fluid line, wherein said carrier gas mixes with said desorbed target species in said chamber to form a first mixture; feeding said carrier gas into said internal bore by way of a second fluid line, wherein said carrier gas mixes with said desorbed target species in said internal bore to form a second mixture; passing said first mixture and said second mixture to a detector; and analyzing said first mixture and said second mixture.
